This assembly-sequence bridge model section was produced for an engineering competition. Something seemingly so simple was actually a bit tricky as the model was required to maintain a higher tolerance in the construction of the parts for demonstration of the assembly of every part – a precision puzzle, if you will. Bright colors were used to identify and distinguish the different elements that would be discussed in the presentation. The engineers were not so sure of the value of this model, but in the end, the clients in Scotland apparently liked it so much that they asked if they could keep it.
